John, thanks for the additional info. Now I understand what you did.
For those who aren't aware, and to back up what John mentioned, using balanced interconnects (if your equipment allows) between (especially) cartridge > phono preamp > preamp, or CDP/DAC > preamp, almost always results in better sonics. (Phono cartridges, whether MC or MM are inherently balanced output devices anyway.)
I mention this because balanced ICs are often only discussed in the context of long runs between preamp and amp (to eliminate noise.) And often people forget (or don't even realize) that balanced circuits usually provide more signal strength as well.
